A creeping or decumbent annual. Culms creeping to ascending, 20–50 cm., glabrous, nodes dark and glabrous. Leaf sheaths loosely to densely covered with bulbous based bristles, smooth to scaberulous. Ligule up to 2.5 mm. long, truncate, entire. Leaf laminae 3–13 × 0.3–0.8 cm., linear, flat, loosely to densely hairy and sometimes scaberulous on both surfaces, often with a few bulbous based bristles near the base, scabrous along the margin. Inflorescence composed of (2)3–14 racemes, (3)5–10 cm. long, sometimes in a basal whorl of 3–5 racemes, the other racemes solitary along the well developed common axis. Rhachis triquetrous, winged, up to 0.5 mm. broad, smooth to scaberulous, with scabrous margins. Pedicels 2-nate, 0.5–3 mm. long, triangular, scabrous, slightly broadened at the apex. Spikelets 1.7–2.1 mm. (subsessile spikelets) and 2.0–2.3 mm. long (pedicelled spikelets), oblong-lanceolate. Inferior glume short, truncate, nerveless, often poorly developed. Superior glume 2/3–3/4 of the spikelet, sometimes nearly as long, 3-nerved, appressed hairy, hairs fine, smooth, acute, hyaline. Inferior lemma as long as the spikelet, oblong, 7-nerved, appressed hairy. Superior lemma as long as to somewhat shorter than the spikelet, acute, pale to dark brown, often purplish tinged. |
